What is the Boston Celtics closing lineup?
Marcus Morris
Speaking of versatility, newly-acquired forward Morris is one player that fits the bill. Morris can play anywhere from small forward to small-ball center.
With Horford on the floor, Morris gets to play the four, which is the position that fits him most in the modern NBA.
In Detroit, Morris primarily played small forward. The only way he plays small forward in Boston is when Stevens goes big with Horford and Baynes (which should be a rare occurrence).
According to basketball reference, the last year the Morris primarily played power forward was 2014-15 with the Suns. That season, Morris averaged 6.8 rebounds per 36 minutes. He will be a valuable asset to close games if he can provide that rebounding and solid defense.
Morris should close against bigger lineups when the Celtics need more size and length defensively.
